VALVE.

Application filed June 18, 1915, Serial No. 34,903.

To all whom it may concern:

Be it known that I, JOHN J. MGINTYRE, a subject of the King of England,residing at Inverness, in the Province of Nova Scot1a and Dominion ofCanada, have invented certain new and useful Improvements in Valves, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to linings for valves and construction of valvesand the like wherein the linings and working portions of the valves areformed of wood, especially treated for use in connection with pumps andthe like.

Another object of this invention is the production of a simple andefficient means whereby the staves forming the lining for the valve willbe firmly clamped against the inner walls of the valve without thenecessity of employing means other than the working portions of thevalve itself.

With these and other objects in view, this invention consists of certainnovel combinations, constructions, and arrangements of parts as will behereinafter fully described and claimed.

In the accompanying drawing Figure 1 is a vertical section through thevalve.

Fig. 2 is a top plan view of the cover of the valve.

Fig. 3 is a side elevation, partly in section, of the valve seat.

Referring to the accompanying drawing by numerals it will be seen that ldesignates the outer portions of the valve casing which is provided withan inner cone-shaped pocket 2. The casing 1 is provided with an aperture3 extending through the bottom thereof in which is placed a wooden valveseat 4; especially treated to resist chemical action. The valve seat 4is provided with an annular flange 5 upon the bottom end thereof uponwhich is placed a metallic extension band 6 for reinforcing the valveseat and preventing the same from splitting. An annular flange 7 isformed upon the casing 1 and a plurality of bolts 8 extend through thisflange 7 for firmly anchoring the casing 1 in engagement with thesupport 9.

The casing 1 is provided with a plurality of laterally extending cars 10between which Specification of Letters Patent.

are pivotally mounted the cover engaging bolts 11 upon which nuts 12 arefitted. The bolts 11 fit in the notched portions 13 formed in the cover1% for firmly looking or clamping the cover 141 in engagement with thecasing l. A plurality of substantially inverted U-shaped handles 15 aresecured to the cover or top 14 for permitting the top or cover 1 1 to beeasily and conveniently handled and removed from the casing 1 when sodesired.

The cap 16 is seated upon the top of the casing 1 and is provided with areduced extension 17, which extension is provided with a centrallylocated aperture 18 having a lining 19. The valve 20 is seated upon thevalve seat 4: and is provided with a tapering lower end 21 forfacilitating the seating of the valve 20 within the aperture 22 formedin the valve seat 4. The valve 20 is provided with a reduced neckextension 23 working in the aperture 18, which aperture constitutes aguide for the valve 20.

The casing 1 is provided with a ledge portion 24 upon which ledge[portion is placed a plurality of closely fitting wooden staves 25, theinner ends of which engage the outer face of the valve seat 1 and theouter ends engage the inner faces of the side staves 26. These sidestaves 26 are placed against the inner face of the casing l and it willtherefore be seen that the bottom staves 25 will be firmly wedgedbetween the inner faces of the staves 26 and the outer face of the valveseat 4.

The upper ends of the staves 26 will be clamped against the side wallsof the casing 1 by means of the outer wall of the cap 16, as shown inFig. 1 of the drawing.

From the foregoing description it will be seen that a very simpleandefficient lining and valve construction has been produced for use wherewooden parts are employed for firmly holding the several parts in anassembled relation and presenting a minimum amount of wear thereon.

What I claim is A device of the class described comprising a valvecasing, said valve casing provided with a valve seat extending upthrough a portion of said casing, said valve casing provided with aledge portion adjacent said valve seat, a plurality of wooden stavesfitted upon said ledge portion and abutting against the outer face ofsaid Valve seat, said casing provided With a cone-shaped inner portion,a plurality of staves engaging the inner face of said casing and fittingbetween the inner Walls of said casing and the outer face of saidfirst-mentioned staves, whereby said first-mentioned staves willbe saidledge portion,

firmly held in a Wedge-like position upon a valve mounted upon saidvalve seat, and means for retaining said 10 valve Within said casing;
